A transfer device is provided with an arm and a controller which controls the movement of the arm. The arm has: a first hook which can move forward and backward to and from a first contact position at which the first hook can make contact with a load; a second hook which can move forward and backward to and from a second contact position at which the second hook can make contact with a load; and a third hook which can move forward and backward to and from a third contact position at which the third hook can make contact with a load. The controller lowers a load in a first placement region onto a shelf and lowers a load in a second placement region onto the shelf. After that the controller retracts the arm so that the second hook is separated from the front end of the load having been lowered onto the shelf from the first placement region and so that the second hook is separated from the rear end of the load having been lowered onto the shelf from the second placement region, and then the controller causes the second hook to exit from the second contact position while the second hook is separated from the front end of the load having been lowered onto the shelf from the first placement region, and also while the second hook is separated from the rear end of the load having been lowered onto the shelf from the second placement region.
